Method for predicting release amount of phenol in mainstream smoke of flue-cured tobaccos

Abstract

The invention relates to a method for predicting the release amount of phenol in mainstream smoke of flue-cured tobaccos. The method comprises the following steps of: performing sample pretreatment on the flue-cured tobaccos to be tested through manual tearing, stem removal, shredding; detecting eight chemical components comprising linoleic acid, total sugar, total nitrogen, chlorogenic acid, malonic acid, total polyphenol, tobacco nicotine and volatile acid of a sample to be tested; calculating network values of thirteen nodes of a hidden layer by combining the measurement results of the eight chemical components with the coefficients of each input layer of a model; converting the network values of the thirteen nodes of the hidden layer into the output values of the thirteen nodes of the hidden layer; and calculating to obtain a predicted value of the release amount of the tobacco phenol by combining the output values of the thirteen nodes of the hidden layer with the coefficients of the output layers of the model. According to the method, the content of phenol in the smoke can be predicted through the model, cigarette rolling and smoking machine equipment suction are not required to capture the particle phase substances; and moreover, the accumulated content of possible phenol in the finished cigarette products to be formed in the future can be effectively predicted through the flue-cured tobacco raw materials, so that raw material selection in the production process is guided.

Description

technical field [0001] The invention relates to a method for predicting the release of phenol in mainstream smoke of uncured tobacco leaves, belonging to the technical field of tobacco. Background technique [0002] Phenol is an important harmful substance in mainstream cigarette smoke, and is listed as one of the seven harmful components of cigarette smoke to evaluate the safety of cigarettes. At present, my country has established industry standards for the determination of phenol in mainstream cigarette smoke. However, usually the determination of the content of phenol in flue gas requires more cumbersome steps such as rolling up the sample, suction and capture by smoking machine, and pre-treatment of the captured material before sampling. Relatively speaking, the determination steps of some constant chemical components in tobacco are relatively simple. The phenol in smoke is mainly produced by the cracking of polyphenolic macromolecular compounds in tobacco leaves, and...
